Description

Technical Field

[0001] The invention relates to the technical field of nitrogen generators, and in particular to a container-type nitrogen generator. Background Art

[0002] A container-type nitrogen generator is a device that installs all the equipment required for nitrogen production in a container, and then uses pressure swing adsorption technology to efficiently and portable generate nitrogen. Container-type nitrogen generators generally use high-quality carbon molecular sieves as adsorbents to produce nitrogen from the air under a certain pressure.

[0003] The equipment generally included in the container-type nitrogen generator includes: air compressor, filter, freeze dryer, air storage tank, control cabinet, adsorption tank and buffer tank, etc. In the actual production process, the above equipment needs to be installed in a container. Due to the large number of equipment and the need for pipelines and cables to connect the equipment, the arrangement of the equipment in a limited space is related to the difficulty of equipment assembly and the efficiency of later equipment detection and maintenance. A reasonable arrangement can not only make the equipment assembly efficient, but also more efficient in the later maintenance process. However, in the current products, the arrangement of the equipment in the container-type nitrogen generator is too compact, and a locking installation method is adopted, which makes the equipment maintenance and overhaul more laborious, and it is often difficult to operate in a limited space.

[0014] Optionally, a positioning tube is fixedly connected to one end of the first mounting frame, and a positioning pin matching the size of the positioning tube is fixedly connected to one end of the second mounting frame close to the first mounting frame, and an insertion rod is inserted into both the positioning tube and the positioning pin.

[0015] Optionally, a pulley is fixedly connected to the bottom of the second mounting frame, a slide rail matching the position and size of the pulley is provided at the bottom of the box body, a guide plate is rotatably connected to one side of the box body close to the first door, and a guide groove matching the size of the pulley is provided on the guide plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting the first mounting frame and the second mounting frame, the corresponding equipment installation frame is reserved on the first mounting frame and the second mounting frame. When installing the equipment, the operator does not need to measure and mark the installation position of the equipment separately, but only needs to install the equipment according to the pre-set frame. Such a setting can greatly improve the efficiency of equipment installation. The equipment is installed in the manner set in this application, not only so that there are gaps reserved between the equipment, but also the arrangement order between the equipment is set according to the nitrogen production process. Such a setting makes the equipment more convenient and efficient when laying pipelines and cables, and there will be no disorderly cables and pipelines in the box. In addition, some equipment that needs to be manually controlled, such as air compressors, freeze dryers, control boxes and control cabinets, are installed near the three sets of box doors. Such a setting makes it more convenient for operators to control the equipment, which not only improves the convenience of operation, but also can open the box doors at the corresponding positions during the maintenance of these equipment to perform maintenance work, thereby improving the efficiency of equipment maintenance.

[0018] By setting up an inspection channel, maintenance personnel can complete maintenance work in the inspection channel during the maintenance of the equipment. Since the inspection channel covers the location of all equipment, there is no blind spot for maintenance. The setting of anti-slip grooves can, on the one hand, increase the friction between the soles of the users' feet and the inspection channel to prevent the users from slipping while walking in the box. On the other hand, since the light in the container is dim and the visibility is low, the anti-slip grooves can help users find the path; a low-light lamp is set at the outer edge of the inspection channel to make the edge of the inspection channel clearly visible. The range of the low-light lamp is a safe range and there is no obstacle blocking the area. Therefore, such a setting can make users walk more safely and conveniently in the container, thereby improving the safety of the equipment.

[0019] By setting up the maintenance auxiliary plate, when the maintenance auxiliary plate is needed, the operator pulls the buckle groove at one end of the rotating maintenance auxiliary plate to rotate the maintenance auxiliary plate to a position perpendicular to the bottom of the box body, and then adjusts the telescopic rod to unfold the foot pedal. At this time, the maintenance personnel can step on the foot pedal and use the foot pedal to increase the height of the maintenance personnel. This setting can facilitate maintenance personnel to carry out maintenance work on the equipment and improve the efficiency of maintenance. Moreover, the maintenance auxiliary plate can be hidden and stored on the side of the first mounting frame when not in use, and will not occupy the space of the maintenance channel.

[0020] The locking fixation between the first mounting bracket and the second mounting bracket can be released, so that the second mounting bracket can slide along the slide rail to the outside of the box after the limit is released. This arrangement allows the adsorption tank to be moved from inside the box to the outside of the box, and then the adsorption tank can be repaired, thereby improving the maintenance efficiency of the adsorption tank. During the sliding of the second mounting bracket, the slide rail and the guide plate can guide and limit the second mounting bracket, thereby improving the efficiency of moving the second mounting bracket from inside the box to outside the box, and the operation is labor-saving and there will be no bumps during the movement, thereby improving the safety of the equipment.

[0045] like Figures 1 to 6As shown, an embodiment of the present invention provides a container-type nitrogen generator, including a box body 1, a first box door 101 is installed at one end of the box body 1, a second box door 103 is installed at the other end of the box body 1, and a third box door 102 is installed at one end of the box body 1 close to the second box door 103. A nitrogen making unit is installed in the box body 1, and the nitrogen making unit is used to make nitrogen. The nitrogen making unit includes an air compressor 6, a control cabinet 7, a freeze dryer 8, a filter 9, an adsorption tank 10, a control box 11 and a storage tank 12; a maintenance mechanism, the maintenance mechanism is used to assist maintenance personnel to repair and install the nitrogen making unit, and the maintenance mechanism is connected to the box body 1. The nitrogen making unit provided in this application is different from the existing Some nitrogen making equipment is the same, so the nitrogen making process and working principle of the nitrogen making unit are disclosed here as the prior art, and no further elaboration is made here. Two adsorption tanks 10 and a control box 11 are installed near the first box door 101, the air compressor 6 is installed near the second box door 103, and the control cabinet 7 and the freeze dryer 8 are installed near the third box door 102. The installation positions of the above three boxes correspond to the installation positions of the equipment in the nitrogen making unit. Such an arrangement makes it more convenient for the user to adjust and operate the nitrogen making unit. In the present application, the equipment layout in the nitrogen making unit is reasonable, and reasonable allocation is achieved in a limited space, thereby improving the practicality of the nitrogen making machine.

[0046] As an implementation method in this embodiment, Figures 4 to 7As shown, the maintenance mechanism includes a first mounting frame 2 fixedly connected to the box body 1, a second mounting frame 3 is installed at one end of the first mounting frame 2, a maintenance channel 201 is fixedly connected to the first mounting frame 2, a maintenance auxiliary plate 4 is rotatably connected to the first mounting frame 2, the thickness of the maintenance channel 201 is less than the thickness of the second mounting frame 3, and anti-slip grooves are fixedly connected to the maintenance channel 201. The bottom of the maintenance channel 201 fits with the bottom plate of the box body 1, and a low-light lamp 202 is fixedly connected to the outside of the maintenance channel 201. The low-light lamp 202 and the maintenance channel 201 are fixed by screws. The maintenance mechanism mainly includes a first mounting frame 2 and a second mounting frame 3. The first mounting frame 2 is installed with an air compressor 6, a control cabinet 7, a freeze dryer 8, a filter 9 and a storage tank 12, and the second mounting frame 3 is installed with an adsorption tank 10 and a control box 11. The first mounting frame 2 and the second mounting frame 3 are reserved for corresponding equipment installation frames. When the operator is When installing the equipment, there is no need to measure and mark the installation position of the equipment separately. The equipment only needs to be installed according to the pre-set frame. Such a setting can greatly improve the efficiency of equipment installation. The equipment is installed in accordance with the setting of this application, which not only reserves gaps between the equipment, but also the arrangement order between the equipment is set according to the nitrogen production process. Such a setting makes the equipment more convenient and efficient when laying pipes and cables, and there will be no disorderly cables and pipes in the box 1. In addition, some equipment that needs to be manually controlled, such as: air compressor 6, freeze dryer 8, control box 11 and control cabinet 7 are all installed near the three sets of box doors. Such a setting makes it more convenient for operators to control the equipment, which not only improves the convenience of operation, but also can open the box doors at the corresponding positions during the maintenance of these equipment to perform maintenance work, thereby improving the efficiency of equipment maintenance.

[0047] As described above, by installing the equipment according to the first mounting frame 2 and the second mounting frame 3 provided in the present application, it can be ensured that a certain gap is reserved between the equipment and the equipment, and an inspection channel 201 is set in this gap. The inspection channel 201 consists of two parts, one part is a plate structure with a thickness less than that of the first mounting frame 2, and the other part is a low-light lamp 202 (such as Figure 4As shown in the figure, the reason why a plate with a thickness smaller than that of the first mounting frame 2 is selected as the inspection channel 201 is to reduce the manufacturing cost of the inspection channel 201. Since the inspection channel 201 has a larger coverage area, reducing the thickness of the plate can save materials as much as possible and reduce costs. Anti-skid patterns are provided on the surface of the inspection channel 201. On the one hand, the anti-skid patterns can increase the friction between the soles of the user's feet and the inspection channel 201 to prevent the user from slipping while walking in the box 1. On the other hand, since the light in the container is dim and the visibility is low, the anti-skid patterns can help the user find the path. In addition, in the inspection channel A low-light lamp 202 is set at the outer edge of 201, so that the edge of the maintenance channel 201 can be clearly seen. The range of the low-light lamp 202 is a safe range and there is no obstacle blocking it. Therefore, such a setting can make users walk more safely and conveniently in the container, thereby improving the safety of the equipment; a maintenance channel 201 is set between the equipment, so that maintenance personnel can complete maintenance work in the maintenance channel 201 during the maintenance of the equipment. Since the maintenance channel 201 covers the locations of all equipment, there is no blind spot for maintenance. Such a setting makes the equipment more efficient and safer during the maintenance process, and is worthy of promotion and use.

[0048] In this embodiment, if Figures 4 to 11 As shown, one end of the maintenance auxiliary plate 4 is rotatably connected to a rotating shaft 401, and one end of the rotating shaft 401 is fixedly connected to the first mounting frame 2. An avoidance groove 402 is provided on one side of the maintenance auxiliary plate 4, and a foot pedal 407 is rotatably connected in the avoidance groove 402. A limit plate 408 is fixedly connected to the maintenance auxiliary plate 4, and a buckle groove 403 is provided at the other end of the maintenance auxiliary plate 4. Telescopic cylinders 404 are symmetrically installed on both sides of the maintenance auxiliary plate 4, and a telescopic rod 405 is slidably connected in the telescopic cylinder 404. A gear rod 406 is fixedly connected to the telescopic rod 405. A straight slide groove 409 and a side slide groove 410 are provided on the telescopic cylinder 404, and a stopper 411 is fixedly connected in the side slide groove 410. The material of the stopper 411 is rubber. The size of the side slide groove 410 is consistent with the size of the gear lever 406. An inspection auxiliary plate 4 is also provided on the first mounting frame 2. The inspection auxiliary plate 4 is installed near some equipment with relatively high height. Such equipment is not only high in height but also has high heights of pipes and cables connected between the equipment. This puts pressure on the maintenance work of maintenance personnel. At present, maintenance personnel generally use ladders to inspect such equipment. However, due to the limited space in the container body 1 and the limited gaps between the equipment, it is not only difficult to place the ladder in the container body 1, but also the stability is not good. In the present application, the inspection auxiliary plate 4 can effectively solve such problems; the inspection auxiliary plate 4 is hidden and stored on the side of the first mounting frame 2 (such as Figure 7 and Figure 8As shown in the figure, the maintenance auxiliary plate 4 is rotatably connected to the first mounting frame 2 through the rotating shaft 401. In this state, the gear lever 406 is stored in the side sliding groove 410, and the gear lever 406 contacts the outer side of the foot pedal 407. Since a rubber stopper 411 is provided in the side sliding groove 410, the gear lever 406 will be limited in the side sliding groove 410 by the stopper 411 without the action of external force. Since the side sliding groove 410 is adapted to the size of the gear lever 406, the gear lever 406 cannot slide in the side sliding groove 410, and the telescopic rod 405 cannot slide and retract in the telescopic cylinder 404. With the help of the limiting effect of the gear lever 406, the home pedal can be blocked and limited to prevent the foot pedal 407 from rotating out of the avoidance groove 402; when the maintenance auxiliary plate 4 needs to be used, the operator pulls the buckle groove 403 at one end of the rotating maintenance auxiliary plate 4 to rotate the maintenance auxiliary plate 4 to a position perpendicular to the bottom of the box body 1 (as shown in the figure). Fig. 9 As shown), first rotate the lever 406 to rotate the lever 406 into the straight slide groove 409. At this time, the lever 406 is no longer limited by the side slide groove 410 and can slide in the straight slide groove 409. Therefore, the telescopic rod 405 can also be raised and lowered in the telescopic cylinder 404. Let the telescopic rod 405 slide toward the bottom of the box body 1. The bottom of the box body 1 is provided with a socket that is compatible with the position and size of the telescopic rod 405. The telescopic rod 405 and the maintenance auxiliary plate 404 can be inserted into the socket to realize the telescopic rod 405 and the maintenance auxiliary plate 404. The fixing effect is achieved. When the gear lever 406 no longer blocks and limits the foot pedal 407, since the foot pedal 407 is rotatably connected to the straight slide groove 409, and a torsion spring is arranged in the shaft body of the rotatable connection between the two, the foot pedal 407 can automatically rotate out of the avoidance groove 402 under the action of the torsion spring. Under the action of gravity, the foot pedal 407 will contact the top of the limit plate 408. Under the support and limit action of the limit plate 408, the foot pedal 407 always forms a 90-degree angle with the maintenance auxiliary plate 4 (such as Fig.10 (As shown) At this time, the maintenance personnel can step on the foot pedal 407 and use the foot pedal 407 to increase their height. This arrangement allows the maintenance personnel to use the maintenance auxiliary board 4 to increase their height when repairing some equipment with relatively high heights, thereby facilitating the maintenance work on the equipment and improving the efficiency of maintenance. Moreover, the maintenance auxiliary board 4 can be hidden and stored on the side of the first mounting frame 2 when not in use, and will not occupy the space of the maintenance channel 201. The method of unfolding and using the maintenance auxiliary board 4 here is simple to operate, and the layout is convenient and efficient, and it is worthy of popularization.

[0049] In this embodiment, if Figure 3 , Figure 4 and Figures 12 to 15As shown, one end of the first mounting frame 2 is fixedly connected with a positioning cylinder 203, and one end of the second mounting frame 3 close to the first mounting frame 2 is fixedly connected with a positioning pin 301 that matches the size of the positioning cylinder 203. The positioning cylinder 203 and the positioning pin 301 are both inserted with an insertion rod 204. The bottom of the second mounting frame 3 is fixedly connected with a pulley 302, and a slide rail 104 that matches the position and size of the pulley 302 is provided at the bottom of the box body 1. A guide plate 5 is rotatably connected to one side of the box body 1 close to the first box door 101, and a guide groove 501 that matches the size of the pulley 302 is provided on the guide plate 5. The first mounting frame 2 and the second mounting frame 3 are not an integrated fixed structure. The two are fixed by the positioning tube 203, the positioning pin 301 and the insertion rod 204. The positioning pin 301 on the second mounting frame 3 can be inserted into the positioning tube 203 on the first mounting frame 2. After the two are connected, the insertion rod 204 is inserted into the positioning tube 203 and the positioning pin 301 from top to bottom to achieve the fixing effect of the two. When the first mounting frame 2 and the second mounting frame 3 need to be separated, it is only necessary to pull the insertion rod 204 from bottom to top, and then pull the second mounting frame 3. A pulley 302 is installed at the bottom of the second mounting frame 3, and the pulley 302 is set in the slide rail 104 at the bottom of the box body 1. The size of the pulley 302 is consistent with that of the slide rail 104. This arrangement allows the user to pull the second mounting frame 3 to slide the pulley 302 in the slide rail 104 after the first mounting frame 2 and the second mounting frame 3 are separated, thereby driving the equipment on the second mounting frame 3 to move. The second mounting frame 3 is mainly installed with an adsorption tank 10 and a control box 11. The adsorption tank 10 needs to replace the carbon atoms inside the tank body during the maintenance process. Since the adsorption tank 10 is generally opened from the top, but the tank body of the adsorption tank 10 is relatively high and the height of the box body 1 is limited, it is inconvenient to operate in the box body 1. The second mounting frame 3 is movable here so that the adsorption tank 10 can be moved from the box body 1 to the box body. 1, and then the adsorption tank 10 is maintained, thereby improving the maintenance efficiency of the adsorption tank 10; after the second mounting frame 3 is released from the limit, it can slide along the slide rail 104 until the adsorption tank 10 slides to the position of the guide plate 5, and the guide plate 5 can rotate on one side of the box body 1. After the rotation, one end of the guide plate 5 contacts the ground, and a gentle slope is formed between the guide plate 5 and the box body 1. At this time, the second mounting frame 3 can slide from the inside of the box body 1 to the outside of the box body 1 along the guide plate 5. The setting of the guide plate 5 can improve the efficiency of the second mounting frame 3 moving from the inside of the box body 1 to the outside of the box body 1, and the operation is labor-saving and there will be no bumps during the movement, thereby improving the safety of the equipment.

[0050] The working principle of the technical solution provided by the present invention is as follows:

[0051] When nitrogen needs to be produced, firstly, the air compressor 6, the control cabinet 7, the freeze dryer 8, the filter 9, the storage tank 12 and other equipment are installed on the first mounting frame 2 by means of bolts, and then the adsorption tank 10, the control box 11 and other equipment are installed on the second mounting frame 3. The equipment is installed in the manner set in the present application, not only gaps are reserved between the equipment, but also the arrangement order between the equipment is set according to the nitrogen production process. Such a setting makes the equipment more convenient and efficient when laying pipelines and cables, and there will be no disorderly cables and pipelines in the box body 1. The outside air passes through the air compressor 6, the filter 9, the freeze dryer, the adsorption tank 10 and the storage tank 12 in sequence to finally produce nitrogen.

[0052] When it is necessary to inspect the equipment, the user can first inspect the equipment near the first door 101, the second door 103 and the third door 102 by opening them. Secondly, the user can enter the box body 1 through the second door 103, and then inspect the equipment in the box body 1 along the inspection passage 201. Anti-slip grooves are set on the surface of the inspection passage 201. On the one hand, the setting of the anti-slip grooves can increase the friction between the soles of the user's feet and the inspection passage 201 to prevent the user from slipping while walking in the box body 1. On the other hand, since the light in the container is dim and the visibility is low, the anti-slip grooves can help the user find the path. In addition, a dim light 202 is set at the outer edge of the inspection passage 201, so that the edge of the inspection passage 201 can be clearly seen. The range of the dim light 202 is a safe range and there is no obstruction. Therefore, such a setting can make the user walk more safely and conveniently in the container, thereby improving the safety of the equipment.

[0053] When the maintenance auxiliary plate 4 is needed, the operator pulls the buckle groove 403 at one end of the rotating maintenance auxiliary plate 4 to rotate the maintenance auxiliary plate 4 to a position perpendicular to the bottom of the box body 1, and then rotates the gear lever 406 to allow the gear lever 406 to rotate into the straight slide groove 409. At this time, the gear lever 406 is no longer limited by the side slide groove 410 and can slide in the straight slide groove 409. Therefore, the telescopic rod 405 can also be raised and lowered in the telescopic cylinder 404, allowing the telescopic rod 405 to slide toward the bottom of the box body 1. A socket that is compatible with the position and size of the telescopic rod 405 is provided at the bottom of the box body 1. The telescopic rod 405 is inserted into the socket to achieve the fixing effect of the telescopic rod 405 and the maintenance auxiliary plate 4. When the gear lever 406 no longer blocks and limits the foot pedal 407, the foot pedal 407 and The foot pedal 407 is rotatably connected in the straight slide groove 409, and a torsion spring is arranged in the shaft body of the rotational connection between the two. Under the action of the torsion spring, the foot pedal 407 can automatically rotate out of the avoidance groove 402, and under the action of gravity, the foot pedal 407 will hit the top of the limit plate 408. Under the support and limiting action of the limit plate 408, the foot pedal 407 always forms a ninety-degree angle with the maintenance auxiliary plate 4. At this time, the maintenance personnel can step on the foot pedal 407 and use the foot pedal 407 to increase the height of the maintenance personnel. This arrangement allows the maintenance personnel to use the maintenance auxiliary plate 4 to increase their height when repairing some equipment with relatively high heights, thereby facilitating the maintenance work of the equipment and improving the efficiency of maintenance. Moreover, the maintenance auxiliary plate 4 can be hidden and stored on the side of the first mounting frame 2 when not in use, and will not occupy the space of the maintenance channel 201. The method of unfolding and using the maintenance auxiliary plate 4 here is simple to operate, convenient and efficient in layout, and worthy of popularization and use.

[0054] When inspecting the adsorption tank 10, the user needs to separate the first mounting frame 2 and the second mounting frame 3 first. The user first pulls the insertion rod 204 from bottom to top, and then pulls the second mounting frame 3 to separate the positioning cylinder 203 and the positioning pin 301 from each other. At this time, the second mounting frame 3 can be moved. The pulley 302 is installed at the bottom of the second mounting frame 3, and the pulley 302 is set in the slide rail 104 at the bottom of the box body 1. The size of the pulley 302 and the slide rail 104 are consistent. This arrangement enables the user to pull the second mounting frame 3 to make the pulley 302 on the slide rail 104 after the first mounting frame 2 and the second mounting frame 3 are separated. 4, thereby driving the equipment on the second mounting frame 3 to move. After the second mounting frame 3 is released from the limit, it can slide along the slide rail 104 until the adsorption tank 10 slides to the position of the guide plate 5. The guide plate 5 can rotate at one side of the box body 1. After the rotation, one end of the guide plate 5 contacts the ground, and a gentle slope is formed between the guide plate 5 and the box body 1. At this time, the second mounting frame 3 can slide from the inside of the box body 1 to the outside of the box body 1 along the guide plate 5. The setting of the guide plate 5 can improve the efficiency of the second mounting frame 3 moving from the inside of the box body 1 to the outside of the box body 1, and the operation is labor-saving and there will be no bumps during the movement, thereby improving the safety of the equipment.
